Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Ethyl 2-Propenoate, 2-Hydroxypropyl 2-Propenoate And Methyl 2-Methyl-2-Propenoate is a multi-component acrylic copolymer designed to deliver a balanced profile of film-forming, adhesion, and durability properties. This versatile polymer is engineered to provide excellent performance as a binder or film-forming agent in demanding industrial and specialty coating applications. It is a critical raw material for formulators in the paints & coatings, adhesives, and construction chemical sectors seeking to enhance product performance and reliability.

Application

• Architectural and Decorative Paints: Serves as a primary binder in interior and exterior emulsion paints, providing excellent film formation, scrub resistance, and color retention.
• Industrial and Protective Coatings: Used in metal primers, wood finishes, and general industrial maintenance coatings where durability and adhesion to various substrates are required.
• Adhesives and Sealants: Functions as a key polymer component in water-based pressure-sensitive adhesives (PSAs), construction adhesives, and caulks, offering good tack and cohesion.
• Construction Chemicals: Incorporated into cementitious modifiers, tile adhesives, and waterproofing membranes to improve flexibility, bond strength, and water resistance.
• Textile and Leather Finishes: Used as a coating or finishing agent to provide a protective layer, improve handle, and enhance durability of fabrics and leather goods.
• Paper Coatings: Employed in barrier coatings and functional finishes for paper and board to improve printability, gloss, and resistance to water or grease.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including solids content, viscosity, pH, and mechanical stability to ensure consistent performance and batch-to-batch reproducibility. While produced to general industrial grade specifications, our quality protocols ensure the product meets the high standards required for formulated end-products. Certificates of Analysis (COA) detailing all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Do not freeze. Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent skin formation or evaporation.
